If you can pick between these two abilities for a shape-shifting artificial intelligence unit, which would you pick?

B} morphing into any animals you want it to that were alive in your lifetime - so sadly no dinosaurs - with a dog's playful and safe temperament, as well as optional simulation of land animals' natural environments and instant aquatic simulation for water animals (from beavers to whales)?

Sorry, I totally missed the point of the question. I thought I was the one morphing, I totally missed that shape-shifting A. I. part so I answered the wrong question (apologies for that). After I realized what the actual question was, I wanted to just say I agree with 'elew4too's' (user name) answer here.

A shape-shifting AI unit would just feel like a glorified sex doll to me, regardless of how realistic the transformation was. I would love to see in UV, echolocate, or do some of the other cool things animals do though.
